Time to go back to school

I graduated high school in 2014, I went to college straight away, but only done one year cause my brother left to the army. I quit college for awhile since it was only gonna be my mom working, so I started working helping pay bills, rent, and buy groceries. Now that me, and my mom live with my brother on base taking care of his kids. I thought it's time for me to go back to school and continue on accomplishing my goals, I'm now 22 years old and I take care of the kids full time. My brother works he just got promoted to specialist and I'm so proud of him💯 but I want my mom to be proud of me again. So I applied to a university full time online, so I'm still gonna take care of the kids. I'm that type of person that always puts her family/love ones before herself. I am I mean look at me I quit college for 2 years just to take care of my mom, then my brother, and now it's all 4 of them. My family will always come first to me cause to me their all my world. I'm going back to school for my mom, brother, niece, and nephews. I wanna put a good example on these little ones to never quit on going to school, that it will take you far in life. Medical coding/billing here I come 😌💯
